Unsupervised anomaly detection of nuclear power plants under noise background based on convolutional adversarial autoencoder combining self-attention mechanism

•This study involves an anomaly detection problem of NPPs under a noisy background, which is rarely studied in previous research.•A novel unsupervised anomaly detection method (CAAE-SA) is designed for solving UAD-NPPs.•The self-attention mechanism is proposed to improve the robustness of CAAE-SA.•E...
